For what is worth, I'd agree.

If I remember correct, though, there was the concern of what happens
when migrating a domain from Xen 4.8 --which would have been build with
cirrus by default-- to Xen 4.9 --which, with this, would build the
receiver domain with stdvga... Or is this not an issue / does not
happen?

Regards,
Dario
